ABSTRACT:
A method for the separation of segregations from material mixtures is dissed. The method is particularly suited for the sedimentation of high-melting metal alloys and their impurities. In the method, material mixtures are introduced into the heatable rotor of a centrifuge disposed in a cooled vacuum. The rotor is subjected stepwise to the influence of changing gravitational accelerations as well as to a heat shock treatment varying in temperature level and/or duration. Equipment for execution of the method is also disclosed. The rotor of the centrifuge consists of several layers and includes a basic part whose outer surface is braced by a compound material bandage. The inner surface of the rotor is provided with a heat-deflecting, protective coating. A non-rotating cooling means and a central heat source are accommodated inside the rotor.
